Can you describe the incident mentioned in Chapter 43 where people mistakenly thought Sai Baba had died prior to his actual passing?

Yes, Chapter 43 recounts a specific incident where Sai Baba's followers were misled into thinking he had passed away. According to the text, Baba once raised his life breath to the crown of his head, or Brahmarandhra, for a period of three days. During this time, he was motionless, and people with "certain minds" concluded that this was not a state of Samadhi but death itself. Preparations for his final rites were consequently made. However, Baba suddenly returned to his body, which greatly startled everyone involved, and the chapter promises to tell how that happened.
